What options are available for a friend facing a visa overstay due to hospitalization in Thailand?

A person is seeking advice for a friend who is currently in a quarantine hospital in Thailand and faces an imminent overstay on their visa due to being hospitalized for COVID-19. They entered the country on a 30-day visa exemption, but after testing positive, they were moved to a hospital for quarantine as their medication for diabetes ran out. The inquirer is looking for ways to mitigate the consequences of this overstay, including potential options to avoid the overstay stamp in the passport or lessen the financial penalties incurred upon exiting the country. Various comments from the community suggest that while a medical certificate may help, the opportunity for a medical extension needs to be applied for before the overstay begins, leaving limited options to avoid penalties.
